The EnGenius Neutron Series EWS7928P is a Neutron Series Managed Wireless solution 24-Port Gigabit PoE+ Layer 2 Switch with 4 Dual-Speed SFP ports ideal for Wireless Access Points, VoIP (Voice-over-IP) phones, and IP surveillance applications.
As part of an EnGenius Neutron Series wireless management solution, the EWS7928P through its browser-based GUI (Graphical User Interface) can discover, configure, manage and monitor up to 50 Neutron Series Wireless Access Points. The controller mode of the Switch provides a suite of wireless management features for IT managers to configure Neutron Series Access Points. Features include clustering Neutron Series Access Points in clusters with identical policies, Access Point IP Auto-Discovery, remote Access Point rebooting for hard-to-reach / previously deployed units, and a host of visual monitoring features including topology and floor plan view modes for the mapping out and tracking of networks. The controller also features a statistics section for record traffic tracking and comparison between units or over-time comparisons.
The interface also lets IT managers apply configuration changes to multiple Access Points or the entire network simultaneously. A dashboard provides instant access to a variety of clients, network information, and events, while a real time map displays Access Point locations and network topology for planning and deployment.
Managing the wired portion of the network is also easy using the same browser-based interface. The Switch supports IEEE 802.1p QoS which automatically classifies and prioritizes compliant device traffic to ensure that time sensitive data such as VoIP is forwarded without delay.
It offers 24 Gigabit ports with IEEE 802.3at/af (PoE+) support and 4 SFP slots for fiber uplinks. The 24 Gigabit ports provide seamless connectivity for devices and applications that require high speed network access and reduce bottlenecks that can interrupt communication. The Switch delivers up to 30 watts per port over connected Ethernet cables to power essential devices like Wireless Access Points, IP Cameras, and VoIP (Voice-over-IP) Phone systems, making the EWS7928P a great choice for businesses that need to connect to a wide variety of devices for their company.
The EWS7928P’s 4 SFP slots accept fiber transceivers for extending the wired network beyond the limitation of Ethernet cabling. This is especially useful for schools with satellite classrooms, or for hotels and resorts, or other businesses with multiple building properties.
The EWS7928P includes bracketing hardware for mounting into a switch rack.
Key Features / Benefits:
Simple to Deploy, Use and Manage
Centralized management, quick setup through a web-based user interface. Supports management of up to 50 Neutron Series Access Points. Lets IT managers keep track of, map out, and plan the placement of Neutron Series Access Points and Switches in the network with a visual view of the topology as well as tools to search for and find Neutron Series Access Points via their IP or MAC address. Also gives IT managers and network administrators the visibility they need to monitor, manage and quickly adjust the settings or performance of their network in real time. The feature rich interface displays usage reports for real time and historical client connectivity to each Neutron Series Access Point as well as traffic flow and load over both wired and wireless portions of the network.
PoE+ IEEE 802.3at/af Support
Enables PoE devices like Access Points, Client Bridges, IP Cameras, VoIP telephones and others to be powered directly from the Switch over an Ethernet cable. Up to 30 Watts per port with a total PoE budget of 185 Watts.
4 Dual-Speed SFP Ports
Includes 4 SFP ports to support transceivers for fiber cabling for connectivity to offices, buildings, or other parts of the network that exceed the distance capability of regular Ethernet.
Full-Featured Layer 2 Manageability
VLAN, QoS, IGMP/MLD Snooping, STP/RSTP/MSTP, Link Aggregation Control Protocol (LACP), SNMP v1/v2c/v3, and more.
PoE Management
The Switch's User Interface allows IT managers the ability to allocate just the amount of wattage they need per port to power specific PoE client devices to conserve as much of their Neutron Series Switch’s total PoE budget as possible. Including more Neutron Series Switches to the network gives administrators the ability and versatility to substantially and rapidly scale their networks and to provide just the right Neutron Series Switch necessary to provide wireless connectivity or surveillance in a part of the network previously unserved.
AP Auto IP-Assignment
Assign an IP address range for wireless clients connecting to the network.
Advanced Wireless Settings for Neutron Series Access Points
Supports Band Steering, Fast Handover and Guest Network features.
Cluster Management
Setup and assign Access Points in clusters within your network to manage the group of Access Points as a single wireless network instead of a series of separate devices.
